Abstract
The present invention relates to a process for regenerating adsorbers as used in solvent recovery, for example.
Regeneration is effected in that the adsorbed substances are desorbed according to known processes and a gaseous desorbate stream is produced, that the gaseous desorbate stream is fed into one or several pervaporation modules, that the desorbed substances in the pervaporation modules are removed from the desorbate stream by gas permeation via semi-permeable solubility diffusion membranes, and that the reduced desorbate stream is recirculated to the adsorber.
Preferred embodiments of the process according to this invention use heatable solubility diffusion membranes. A
recovery of the desorbate stream is rendered possible by the process according to this invention, which does not imply a change in state of the entire desorbate stream.
